------------------------------------------
Summary: Incorrect result with two-step aggregate function
Key: ASTERIXDB-2612
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2612
Project: Apache AsterixDB
Issue Type: Bug
Components: COMP - Compiler
Reporter: Dmitry Lychagin
Assignee: Dmitry Lychagin
On a system with 2 nodes and 2 I/O devices on each node the following query
returns wrong result because of the two-step aggregate rewriting:
{noformat}
select m, array_count((from g select value g.t.unique1 limit 3)) cnt
from onektup t
group by unique2 % 2 as m group as g
order by m
{noformat}
Expected:
{noformat}
{ "m": 0, "cnt": 3 }
{ "m": 1, "cnt": 3 }
{noformat}
Actual result.
{ "m": 0, "cnt": 12 }
{ "m": 1, "cnt": 12 }
Dataset: data/wisc/onektup.adm
